Marin - I did not realize until clicking on this one that it's pronounced ma-RIN. I think she would end up dealing with a lifetime of MARE-in unfortunately. Garnet - Definitely a harsher sound than Willow and Veda, but I can see the appealTamsin - A lovely name. I have a negative association though, the bitchy blonde Valkyrie from Lost GirlElidi - love this one, especially the meaning! I think she'd be perfect with Willow and Veda, and your previous mention of ElidiRaine is to die for!Artis - I do feel as if it's a contraction of Artemis. Either that or a boys' name, like a mashup of Artie and OtisSalome - Love, and she has the same softly exotic vibe as your daughters' names. I do agree with PP that if you use Salome you'll be ruling out Solomon for any future surprise boyos. However, if your last baby IS a girl and you love the sound of Solomon, Salome could be a lovely choice.Thora - I like the idea of Thea...Thora is okay. I think I have enough of a feminist streak that I prefer straight-up goddess names to feminizations of god names. Freya, Isis, Demeter, Seshat, Ceres, Eos, Airmid, Rhea, Yemaya, Selene, Themis, Pele, Gaia, and Danu are some examples of exotic but non-frilly goddess names that could work in your sibset (oh, and there's Siv/Sif, the wife of Thor) Bethan - I do feel like this will be mistaken for BethAnn or a Bethany typo...I'm sorry! It's a lovely name...Tressa - Another like for your third daughter, and the similarity to "tresses" makes me think of Rapunzel like plaitsRaine - Quite possibly my favorite from your list, whether as a middle or a first. Love that it honors family, and Willow, Veda, and Raine is an amazing sibset with a cooling, tranquil, zen vibe.

I love your daughters names! And I think you have a great list so far my favourites on there are Marin and Tressa. I would say Bethan (my name is Bethan, and that would be very biased haha)
But just to let you know I've never been mistaken for a Beth-Ann, but where I live Bethan is a known name and only recently double names like Lola-May, Ella-Jo and Cari-Ann have become popular. So no one would have suspected it would be Beth-Ann.

Here are a few names that I think would go great with your girls' names:

I actually wouldn't usually like Raine but I think it fits perfectly with your girls names and has such a nice family connection, it would be my pick. I also think Tamsin and Tressa are lovely. How do you pronounce Elidi?
